ADO.NET can handle concurrency using optimistic concurrency control, which allows multiple users to access the data without locking it.

In a client-server architecture, the client sends requests to the server and displays results.

In a client-server architecture, the application layer is responsible for the user interface.

In a client-server database, the server processes user requests and manages data storage.

In a client-server database, the server is responsible for processing queries.

A foreign key links two tables together by referencing the primary key of another table.

ACID stands for Atomicity, Consistency, Isolation, and Durability, which are the key properties of transactions in a database.

Data independence refers to the ability to change the data structure without affecting the applications that use the data.

Data replication in a distributed database ensures data consistency across all nodes by maintaining copies of the same data in multiple locations.

A deadlock occurs when two transactions are waiting for each other to release locks, preventing both from proceeding.

Data inconsistency can arise in a multiuser database environment when multiple users update the same data simultaneously.

The primary role of a DBMS in a multiuser environment is to manage data storage and retrieval services efficiently.

A foreign key links two tables together, ensures data integrity, and can act as a primary key in another table.

A foreign key is a field (or collection of fields) in one table that uniquely identifies a row of another table.

A foreign key is a field (or collection of fields) in one table that uniquely identifies a row of another table, establishing a link between them.

A foreign key is used to establish a relationship between two tables, linking records in one table to records in another.

Fact tables in a star schema contain transactional data that can be analyzed, often including measures and foreign keys to dimension tables.

Fact tables in a star schema represent transactional data, containing measurable, quantitative data for analysis.

In a star schema, the central fact table is surrounded by dimension tables that provide context to the data.

In a star schema, the central table is the fact table, which contains quantitative data for analysis.

SqlConnection class is used to establish a connection to a SQL Server database in ADO.NET.

In an ER model, a diamond shape represents a relationship between entities.

In an ER model, an entity represents a real-world object or concept that can have data stored about it.

A multi-valued attribute is represented as a double oval in an ER diagram.

A primary key is typically represented by underlined text in an ER diagram.

In an ER diagram, a diamond shape represents a relationship between entities.

A one-to-many relationship is typically represented with a crow's foot notation.

A circle in an ER model represents an attribute of an entity.

In an ER model, a diamond shape represents a relationship between entities.

A solid line between two entities indicates a strong relationship in an ER model.
